Abstract
The utility model relates to a vibration damping sleeve for a car plate spring in the field of a car vibration damping system. The vibration damping sleeve for the car plate spring comprises a cylindrical rubber sleeve; and one end of the cylindrical rubber sleeve has a beading structure, and a wear-resistant bushing is fixedly lined on the inner wall of the rubber sleeve. For the vibration damping bush adopting the structure, the direct contact surface between a pin shaft for connecting a car body and the plate spring and the vibration damping sleeve is an internal cylindrical surface of the wear-resistant bushing, so that the wear resistance of the contact surface is improved, and the good wear-resistant and vibration damping properties of the connection part of the car body and the plate spring can be maintained; in addition, after the wear-resistant bushing is additionally arranged, the whole compression resistance property of the vibration damping bush for the car plate spring is also improved; therefore, compared with the prior art, the vibration damping bush for the car plate spring has good wear resistance and compression resistance, and leads the car to maintain good vibration damping and stable driving properties.
Description
Technical field
The utility model relates to the automobile shock system, particularly a kind of leaf springs of car shock absorbing sleeve of vehicle body and leaf spring connection part.
Background technique
Automobile is the important transport facility of the modern life, and automobile operation is to weigh the important indicator of automotive performance with the stability of going, and the quality of the damping performance of shock mitigation system directly influences the stationarity of automobile between automotive body and the axletree.The effect of shock mitigation system mainly is: when automobile running; Relax the road surface and pass to the impact of vehicle body; The vibration of the bearing system that decay causes thus, the stationarity of assurance automobile running, the kinetic characteristic of assurance wheel held stationary when Uneven road and load change; Guarantee the stability of automobile operation, make automobile obtain the ability that high-speed smooth is gone.Usually, the leaf spring elasticity through many groups of stacks between vehicle body and the axletree couples together, and concrete connection is become: the leaf springs of car of many group stacks is rotationally connected through bearing and axletree, and leaf spring adopts bearing pin to be connected with chassis; In the existing technology,, on bearing pin, be set with rubber bushing earlier, and then be fixedly connected with pin-and-hole for improving the damping performance of bearing pin joint; But in use, this rubber bushing compressive strength is low, and shock resistance is poor, and wearing and tearing are very fast; The vibration aggravation of joint, wearing and tearing back, the stationarity of automobile reduces, and simultaneously, it is big that the vibrating noise in the automobile running becomes; For this reason, need often to change rubber bushing, increased the maintenance cost of automobile.
The model utility content
The utility model provides a kind of wear-resisting property and compression resistance better to the deficiency of existing technology, makes the leaf springs of car shock absorbing sleeve of the good damping performance of automobile maintenance.
The purpose of the utility model is achieved in that a kind of leaf springs of car shock absorbing sleeve; Comprise that an end has the cylindrical shape rubber sleeve of convex shoulder structure; Said rubber sleeve inwall fixedly is lined with anti-wearing liner, adopts the leaf springs of car shock absorbing sleeve of this structure, and vehicle body is connected the bearing pin that uses and the shock absorbing sleeve direct contact surface inner cylindrical surface as anti-wearing liner with leaf spring; Can improve the wear-resisting property of surface of contact like this; Make the connection part of vehicle body and leaf spring keep well wear-resisting and damping performance, set up this anti-wearing liner simultaneously after, the whole compressive strength of leaf springs of car shock absorbing sleeve has also improved; Therefore compared with prior art, the leaf springs of car shock absorbing sleeve of the utility model has good abrasion resistance and compression resistance, makes the good damping of automobile maintenance and the performance of smooth-ride.
For ease of making, said anti-wearing liner is the high molecular abrasion-proof material; For guaranteeing leaf springs of car shock absorbing sleeve and pin-and-hole connection stability, said rubber sleeve slightly goes out the convex shoulder plane near the end face of convex shoulder one end, and the other end of rubber sleeve is provided with one section outer round table surface of the taper of shrinking at an angle near the end.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the leaf springs of car of employing the utility model and the schematic representation that is connected of vehicle body.
Wherein, 1 bearing pin; 2 leaf springs of car shock absorbing sleeves; 201 end faces; 202 convex shoulders; 203 rubber sleeves; 204 anti-wearing liners; 205 round table surface; 3 vehicle bodies; 4 leaf springs.
Embodiment
As shown in the figure, be the leaf springs of car shock absorbing sleeve of the utility model, comprise that an end has the cylindrical shape rubber sleeve 203 of convex shoulder 202 structures, rubber sleeve 203 inwalls fixedly are lined with anti-wearing liner 204; The employing high molecular abrasion-proof material of the anti-wearing liner 204 of the utility model is processed; Rubber sleeve 203 slightly protrudes the convex shoulder plane near the end face 201 of convex shoulder 202 1 ends, and the other end of rubber sleeve 203 is provided with one section outer round table surface 205 of the taper of shrinking at an angle near the end.
In the work, vehicle body 3 is connected through bearing pin 1 with leaf spring 4, and bearing pin 1 its periphery before the pin-and-hole of packing into is set with the leaf springs of car shock absorbing sleeve 2 of the utility model; Like this; Bearing pin 1 is that the wear-resisting property of surface of contact has improved like this in the anti-wearing liner 204 interior cylinders with leaf springs of car shock absorbing sleeve 2 direct contact surfaces, makes vehicle body 3 and leaf spring 4 connection parts keep well wear-resisting and damping performance; After having set up this anti-wearing liner 204 simultaneously, the whole compressive strength of leaf springs of car shock absorbing sleeve 2 has also improved.
The utility model is not limited to the foregoing description; For example anti-wearing liner also can adopt wear resistant alloy material to process; All on the basis of the disclosed technological scheme of the utility model; Those skilled in the art does not need performing creative labour just can make some replacements and distortion to some technical characteristicss wherein according to disclosed technology contents, and these replacements and distortion are all in the protection domain of the utility model.
Claims (3)
1. a leaf springs of car shock absorbing sleeve comprises that an end has the cylindrical shape rubber sleeve of convex shoulder structure, it is characterized in that said rubber sleeve inwall fixedly is lined with anti-wearing liner.
2. leaf springs of car shock absorbing sleeve according to claim 1 is characterized in that, said anti-wearing liner is the high molecular abrasion-proof material.
3. leaf springs of car shock absorbing sleeve according to claim 1 and 2 is characterized in that, said rubber sleeve is provided with the end face of slightly giving prominence to the convex shoulder plane near convex shoulder one end, and the other end of rubber sleeve is provided with one section outer round table surface of the taper of shrinking at an angle near the end.
