Abstract
The utility model relates to a novel single-lever double-H transmission cover plate assembly, which comprises a dust shield, a gear shifting shaft, a high-gear spring, pins, a gear selecting/shifting shifting block, a reverse-gear spring, a stopping plunger piston and a damping spring. The cover plate assembly is characterized in that the gear shifting shaft is coupled with the gear selecting/shifting shifting block via the pins in interference fit; the front side and the back side of the gear selecting/shifting shifting block adopt a fan-shaped cylindrical surface structure or a conical surface structure; and the gear selecting/shifting shifting block is interlocked with the damping spring, the stopping plunger piston, the high-gear spring and the reverse-gear spring, so as to conduct not only the limiting on a high-gear/reverse-gear stopping plunger piston, but also the control on a double-H mechanical control valve. The utility model is suitable for a single-lever single-H, double-lever double-H, or double-lever single-H transmission cover plate assembly.
Description
Technical field:
The utility model relates to the two H structure speed changer top cover assemblies of a kind of novel single pole, belongs to auto parts and components.
Background technique:
At present, the remote shifting of automotive transmission top cover assembly is handled form and is generally adopted mono-lever control formula top cover assembly (being called for short the single pole top cover) or two kinds of structures of two lever operation formula top cover assemblies (being called for short two masthead lids).
Single pole top cover shifting structure generally adopts gearshift axle and shifting shifting block to connect by woodruff key, and with the structural type of lock screw and the locking of steel wire locking wire, gearshift axle and shifting block are fastened into an integral body.Overcome resistances such as damping spring, five or six retaining springs or the spring that reverses gear during block selecting, finish the block selecting action.
The working principle of this structure is: during block selecting, the gearshift axle drives the block selecting driving lever, carries out left and right sides to-and-fro motion along the gearshift shaft centre line, overcomes resistances such as damping spring, five or six retaining springs or the spring that reverses gear simultaneously, finishes the block selecting action.When choosing a certain gear, the gearshift axle drives the block selecting driving lever, carries out swing along the gearshift shaft centre line and realizes gearshift.
Utilize this structure when realizing the two H structure top cover of major-minor case speed changer single pole, the shifting shifting block is difficult for realizing simultaneously the functions such as control of the spacing of the high gear/stop plunger that reverses gear and two H mechanically controlled valves (high to low gear switch with).
Summary of the invention:
The purpose of this utility model is to provide a kind of novel single pole two H structure speed changer top cover assemblies, it is at said structure form narrow limitation in actual applications, the section of two fan-shaped cylinders before and after the shifting shifting block or conical surface is designed to needed geometrical shape, and under the mating reaction of damping spring, stop plunger, high gear spring, the parts such as spring that reverse gear, can realize the functions such as control of the spacing of the high gear/stop plunger that reverses gear and two H mechanically controlled valves simultaneously.
The technical solution of the utility model is achieved in that the two H structure speed changer top cover assemblies of a kind of novel single pole, comprises dust-proof cover, gearshift axle, shifting shifting block, pin, stop plunger, high gear spring, the spring that reverses gear, blind nut, outer snap ring, spring stop piece, damping spring, end cap; It is characterized in that: the gearshift axle adopts the pin riveted joint of interference fit to connect with the shifting shifting block; Fan-shaped cylinder or conical surface structure are adopted in the front and back of shifting shifting block, and link with damping spring, stop plunger, high gear spring, the spring that reverses gear.Be applicable to single pole list H, the two H of two bar, the isostructural speed changer top cover assembly of two bar list H.
The beneficial effects of the utility model are:
(1), the utility model uses fan-shaped cylinder or conical surface structure and riveted joint dexterously: by the pin riveted joint of gearshift axle with the shifting shifting block, the gearshift axle drives shifting shifting block move left and right, fan-shaped cylinder of former and later two of shifting shifting block or conical surface structure, the resistance of damping spring, gear feel spring can be realized overcoming, functions such as two H mechanically controlled valves can be realized controlling again.
(2), the utility model can be realized modularization, on the original basis, just can realize that by very little change the speed changer shifting of single pole list H structure handles form, can realize that by suitable change and module combinations the isostructural speed changer shifting of two H, the two bar list H of two bars handles form.

Embodiment:
Below in conjunction with accompanying drawing the utility model is further described: the two H structure speed changer top covers of novel as shown in Figure 1 single pole comprise compositions such as dust-proof cover 1, oil sealing 3, gearshift axle 4, lining 6, top cover 7, blind nut 8, high gear spring 9, pin 10, shifting shifting block 11, the spring 12 that reverses gear, stop plunger 13, lining 14, outer snap ring 15, spring stop piece 16, damping spring 17, O shape ring 18, spring stop piece 19, outer snap ring 20, end cap 21, mechanically controlled valve 22; It is characterized in that: gearshift axle 4 adopts the pin riveted joint of interference fit to connect with shifting shifting block 11.Fan-shaped cylinder or conical surface structure are adopted in the front and back of shifting shifting block 11, its section is designed to needed geometrical shape, and under the mating reaction of damping spring 17, stop plunger 13, high gear spring 9, the parts such as spring 12 that reverse gear, realize the functions such as control of the spacing of the high gear/stop plunger that reverses gear and two H mechanically controlled valves simultaneously.
During block selecting, shifting shifting block 11 is under the drive of gearshift axle 4, carry out left and right sides to-and-fro motion along gearshift axle 4 center lines, overcome resistances such as damping spring 17, high gear spring 9 or the spring 12 that reverses gear simultaneously, also can control high to low gear mechanically controlled valve 22 during by the high to low gear transition zone, finish the block selecting action.When choosing a certain gear, gearshift axle 4 drives the shifting shifting block 11 that is riveted together with it, carries out swing along the gearshift shaft centre line and realizes gearshift.
