Abstract

A kind of telescopic lever speed-changer operation device and heavy-duty car are provided, it is made up of dust cover assembly, executor assembly, telescopic lever assembly, screw rod, flexural pivot and block selecting support.Dust cover assembly and executor assembly are directly installed at gearshift hole, thoroughly solve the problems, such as that sealing is bad at driver's cabin gearshift hole.Executor assembly lower swing arm is pendulum structure and has free clearance, so as to reach the phenomenon for preventing off-gear, falling gear.Telescopic lever assembly includes the flexible mobile jib of front end and the tail pipe of rear end.When driver's cabin is fallen, the lock of telescopic lever assembly front end locks flexible mobile jib, and now telescopic lever assembly is rigid structure, will not produce telescopic effect.Telescopic lever assembly front end connects executor assembly, and rear end is connected by flexural pivot with shift of transmission rocking arm, when driver's cabin is dug, hand oil pump is opened, and in the presence of hydraulic oil, lock is opened, flexible mobile jib becomes the Multi section bar of antenna-like, is overturn with driver's cabin and executor assembly.

Description

Telescopic lever speed-changer operation device and heavy-duty car
Technical field
The utility model belongs to speed-changer operation system regions, and in particular to a kind of telescopic lever speed-changer operation device.
Background technology
In the conventional steerable system of heavy-duty car, stiff rod, which manipulates, has the shortcomings that sealing is bad, and flexible shaft manipulation has The shortcomings that reliability is not high.The development and application of telescopic lever steerable system can meet user to sealing and reliability simultaneously Demand.Application prospect is than wide.
Utility model content
The purpose of this utility model is to provide a kind of good airproof performance, reliability height, light, comfortable and structure letter of shifting gears Single, telescopic lever speed-changer operation device and heavy-duty car easy for installation.
Telescopic lever speed-changer operation device of the present utility model is mainly by dust cover assembly, executor assembly, flexible drawing Bar assembly, screw rod and flexural pivot composition.
Dust cover assembly and executor assembly are directly installed at the gearshift hole of cab floor, thoroughly solve driver's cabin The problem of sealing is bad at gearshift hole.Executor lower swing arm is designed as pendulum structure, has 3mm free clearance.It can prevent Vehicle when being travelled in bumpy road off-gear, fall the phenomenon of gear, realize the reliability of gearshift.Because bumpy road is produced to tire Raw excitation can cause the frequency on chassis and cab vibration and amplitude inconsistent, so as to produce impact to speed-changer operation system Power, the free clearance at executor assembly lower swing arm can absorb the energy of impulsive force, prevent off-gear so as to reach, fall showing for gear As.
Telescopic lever assembly is made up of the flexible mobile jib of front end and the tail pipe of rear end.When driver's cabin is fallen, telescopic lever The lock of assembly front end locks flexible mobile jib, and now telescopic lever assembly is rigid structure, will not produce telescopic effect.It is flexible Rod assembly front end connects executor assembly, and rear end is connected by flexural pivot with shift of transmission rocking arm, to transmit driver The choosing of operation, gear shifting force.When driver's cabin is dug, hand oil pump is opened, in the presence of hydraulic oil, telescopic lever assembly front end Lock is opened, and flexible mobile jib becomes the Multi section bar of " antenna " shape, overturn with driver's cabin and executor assembly.Tail pipe is specification For 35 × 6 No. 20 cold-drawn round steel bending formings, meet shift of transmission performance requirement by theoretical calculation and road conditions experiment.
On the one hand to provide a kind of telescopic lever speed-changer operation device, it includes manipulating the technical solution of the utility model Device assembly, dust cover assembly, telescopic lever assembly, flexural pivot, screw rod, block selecting support;
- executor assembly the lower swing arm is using pendulum model structure design and has free clearance, the dust cover assembly It is arranged on executor assembly at the gearshift hole of cab floor;
- telescopic lever the assembly uses split-type structural, and telescopic lever assembly includes the flexible mobile jib of front end, rear end Tail pipe;
The flexible mobile jib of the front end of-telescopic lever assembly is connected with the executor assembly, the rear end of the tail pipe It is connected by flexural pivot with shift of transmission rocking arm;
- described screw rod one end connects the tail pipe, the other end connects the speed changer gear selecting support.
Further, mobile jib front end is stretched provided with lock, for the stretching structure with locking flexible mobile jib.
Further, the flexible mobile jib is the Multi section bar stretching structure of Antenna Type.
Further, the tail pipe is bending forming, and it includes horizontal segment and what is seamlessly transitted is in not to be with horizontal direction The inclined tube section of zero angle.
Further, the flexible mobile jib has 1100mm maximal dilation amount.
Further, the tail pipe is No. 20 cold-drawn round steel bending formings that specification is 35mm × 6mm.
Further, the pendulum structure has 3mm free clearance.
For the another aspect of the technical solution of the utility model to provide a kind of heavy-duty car, it uses above-mentioned telescopic lever Speed-changer operation device.
Therefore the utility model has good airproof performance, and reliability is high, light, comfortable and simple in construction, installation side of shifting gears Just the advantages of.
Brief description of the drawings
Fig. 1 is the structural representation of one embodiment of telescopic lever speed-changer operation device of the present utility model.
In figure:1. dust cover assembly;2. executor assembly;3. telescopic lever assembly;4. screw rod;5. flexural pivot;6. choosing Keep off support.
Embodiment
In conjunction with drawings and the specific embodiments, the utility model is further described.
The utility model is as shown in drawings:Telescopic lever speed-changer operation device is mainly total by dust cover assembly, executor Into, telescopic lever assembly, screw rod and flexural pivot composition, dust cover assembly and executor assembly be arranged on cab floor gearshift At hole.Telescopic lever assembly front end is connected with executor assembly, and rear end is connected by flexural pivot with shift of transmission rocking arm.Spiral shell Bar is connected as fulcrum, left end connection telescopic lever assembly, right-hand member with speed changer gear selecting support.Executor assembly lower swing arm uses Pendulum model structure design, the pendulum structure have 3mm free clearance.
Telescopic lever assembly uses split-type structural, and telescopic lever assembly includes flexible mobile jib, the tail pipe of rear end of front end; Flexible mobile jib is the Multi section bar stretching structure of Antenna Type, and tail pipe is bending forming, it include horizontal segment and seamlessly transit with Horizontal direction is in the inclined tube section for the angle being not zero.The flexible mobile jib of the front end of telescopic lever assembly is connected with executor assembly, The rear end of tail pipe is connected by flexural pivot with shift of transmission rocking arm;
