Abstract
Automobile steering shaft and column tube mechanism comprises a universal joint fork, fastening piece; fastening connection hole in universal joint fork is aperture structure; fastening piece is fittably mounted with universal joint fork fastening connection hole and fastens the universal joint fork and transmission axis through fastening connection hole and screw of bolt and nut, thereby universal joint fork and transmission axle is firmly connected; only the bolt and nut is needed to replace periodically for detaching, which lengthens service life of universal joint fork, solves problem of untight screw because the universal joint fork adopts connection of tapped bore and bolt in existing automobile steering shaft and column tube mechanism, and shortened service life of universal joint fork because the universal joint fork tapped bore is subject to damage; automobile steering shaft and column tube mechanism have strong practicability.
Description
Technical field
The utility model relates to a kind of steering axles and column jecket mechanism, belongs to car chassis steering control mechanism technical field.
Background technology
Present employed automobile, because system of vehicle transmission and the needs that turn to, a large amount of joint yokes that use in steering axles and column jecket mechanism, and the structure of the tightening connecting bore that is adopted on joint yoke at present is, half is the unthreaded hole structure, half is a thread pore structure, when needs are fastening, the mode that adopts bolt to be connected with the tapped bore of joint yoke, bolt is from the unthreaded hole end is packed the tightening connecting bore of joint yoke into, bolt is partly tightened with the tapped bore of the tightening connecting bore of joint yoke and is connected then, such connection structure mode, from the angle of installing still eaily, but reality use discovery bolt is direct and the tapped bore of the tightening connecting bore of joint yoke is partly tightened the stubborn not tight phenomenon of ease of connection generation, and joint yoke damages easily, mainly be that bolt is through after repeatedly installing and removing, the easy damage of tapped bore part of the tightening connecting bore of joint yoke is caused, so causing joint yoke easily scraps owing to the tapped bore of tightening connecting bore partly damages, such connection structure also causes the vehicle phenomenon of bolt looseness in use easily simultaneously, causes and twists not tight phenomenon.
Summary of the invention
The utility model provides a kind of steering axles and column jecket mechanism of novelty, the tightening connecting bore of joint yoke adopts unthreaded hole and bolt and nut connection structure, improved locking torque, realize the reliable locking of joint yoke and castellated shaft, prevent the loosening and prolongation joint yoke of joint yoke service life purpose.
The technical solution adopted in the utility model is:
Steering axles and column jecket mechanism, comprise: joint yoke 1, fastener 2, tightening connecting bore 3 in the joint yoke 1 is the unthreaded hole structure, and fastener 2 cooperates installation with the tightening connecting bore 3 of joint yoke 1, fastener 2 by tightening connecting bore 3 with joint yoke 1 and transmission shaft tightening.
The beneficial effects of the utility model are:
Steering axles of the present utility model and column jecket mechanism, owing to be to adopt bolt and nut joint yoke is fastening by the tightening connecting bore of joint yoke, make firm and reliable connection between joint yoke and the transmission shaft, when dismounting, need only the demounting bolt nut, and the periodic replacement bolt and nut gets final product, improved the service life of joint yoke, solved joint yoke in existing steering axles and the column jecket mechanism owing to adopt tapped bore to be connected to be caused with bolt twist not tight phenomenon and the joint yoke tapped bore damages the problem that makes joint yoke shortening in service life easily, have very strong practicality, thereby market outlook are boundless.

The specific embodiment
As Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, shown in Figure 6.
Steering axles and column jecket mechanism, comprise: joint yoke 1, fastener 2, tightening connecting bore 3 in the joint yoke 1 is the unthreaded hole structure, and fastener 2 cooperates installation with the tightening connecting bore 3 of joint yoke 1, fastener 2 by tightening connecting bore 3 with joint yoke 1 and transmission shaft tightening.
Joint yoke 1 is set on the transmission shaft, the bolt of fastener 2 is packed in the tightening connecting bore 3, the thread end of bolt is loaded onto pad and nut, turn nuts and bolt, fastener 2 is tightened, thereby, make joint yoke 1 firm being installed on the transmission shaft, thereby being installed in steering axles and the column jecket mechanism with two joint yoke 1 safety with joint yoke 1 and drive shaft sleeve dress bonded assembly hole chucking.
When dismantling joint yoke 1, as long as loosening fasteners 2, just joint yoke 1 can be pulled down from transmission shaft, be prolongation the service life of joint yoke 1 like this, even part has damage, also be to damage fastener 2, the replacing of fastener 2 very easy and and cost very cheap, unusual saving of work and time.
Transmission shaft end and medium position in steering axles and column jecket mechanism respectively are provided with a joint yoke 1, and these two joint yoke 1 structures are identical, only are sizes, and are also identical with the installation connection mode of transmission shaft.
Claims (2)
1, a kind of steering axles and column jecket mechanism, comprise: joint yoke (1), fastener (2), it is characterized in that: the tightening connecting bore (3) in the joint yoke (1) is the unthreaded hole structure, fastener (2) cooperates installation with the tightening connecting bore (3) of joint yoke (1), fastener (2) by tightening connecting bore (3) with joint yoke (1) and transmission shaft tightening.
