Abstract
The utility model disclose a car rear bridge assembly belonging to the field of car body supporting devices, which resolves the problem of poor fastness, poor car security, and poor comfort when the car rear bridge assembly is connected with the car body, wherein, a car rear bridge assembly comprises a rear bridge body and connecting poles respectively arranged on the tow ends of the rear bridge body, installing seats are arranged on every connecting pole. The utility model is characterized in that the connecting pole bends to the outer side of the bridge body, an angle alpha between 100 degrees and 160 degrees is arranged between the axes of the two installing seats.
Description
Technical field
The utility model relates to a kind of bearing set of auto body, relates in particular to the back axle assembly on a kind of automobile.
Technical background
The structure of existing vehicle rear axle assembly comprises the back axle body, is located at the joint pin at back axle body both ends respectively, all is fixedly connected with a mount pad on each joint pin, and the vehicle body of automobile is connected with this mount pad by binding bolt.Wherein, joint pin is vertically to be located on the back axle body.On the back axle body, except above-mentioned joint pin and mount pad, also has the position that some are connected with shock absorber, in order to the automobile stationarity of vehicle body in the process of moving.Automobile in the process of moving, if run into that road conditions are bad, brake or when quickening, the pressure of back axle body on being subjected to the vehicle body vertical direction, also can be subjected to the power on the vehicle body horizontal direction, under the effect of shock absorber, vehicle body can be done small size vibration on the back axle body in addition.Vehicle body just with between the mount pad is captiveed joint, and with other vibration damping between be connected for elasticity, therefore, when automobile travels under above-mentioned improper situation, stressed complexity between vehicle body and the mount pad, the binding bolt that connects vehicle body and mount pad easily takes place to become flexible, and this both can have influence on the driving safety of automobile, and the traveling comfort that the while automobile is driven also can greatly reduce.
Summary of the invention
For overcoming the above-mentioned defective that existing vehicle rear axle assembly is had, the utility model technical issues that need to address: a kind of later-model vehicle rear axle assembly is provided, have connectivity robustness preferably between mount pad on it and the vehicle body, improved the safety and the traveling comfort of running.
For solving the problems of the technologies described above, the technical solution of the utility model: a kind of vehicle rear axle assembly, comprise the back axle body, be located at a joint pin on the back axle body two ends respectively, on each joint pin, be equipped with a mount pad, it is characterized in that, described joint pin has an angle α towards the outside curve of back axle body between the axis of described two mount pads, 100 °＜α＜160 °.Automobile vehicle body in the process of moving is in an unsure state often, the power that vehicle body is applied on the mount pad is relatively complicated, pressure on the existing vertical direction, thrust on the horizontal direction is also arranged, these two kinds of power combineds action are after on the mount pad, be oblique acting on the mount pad its formed making a concerted effort, joint pin obliquely is provided with on the back axle body, and has certain included angle between the axis of two mount pads, mount pad obliquely is arranged on the end of joint pin, the resultant direction of suffered vehicle body can be tending towards the axial of mount pad on the mount pad, be located at binding bolt on the mount pad in the automobile traveling process, its radial force is little, and binding bolt can connect vehicle body and mount pad more securely.
As preferably, 129 °＜α of described angle＜130 °, at this moment, be subjected to be decomposed into joint efforts on the vehicle body mount pad axial direction and binding bolt radial direction on the mount pad, automobile is in traveling process, it directly upwards is subjected to a predetermincd tension binding bolt of connection vehicle body and mount pad, and binding bolt has higher connectivity robustness.
As preferably, described mount pad is perpendicular to the end of joint pin, is convenient to mount pad and is connected with separately joint pin, has the conformability of installation site preferably between two mount pads and the joint pin.
As preferably, the sweep of described joint pin is an arc-shaped transition.Automobile in the process of moving, joint pin in-to-in distribution of stress situation is complicated, the sweep of joint pin is an arc-shaped transition, can avoid joint pin internal stress concentration phenomenon effectively, has improved the stability in use of joint pin.
Therefore, the beneficial effects of the utility model:
Because joint pin is arranged on the end of back axle body laterally agley, and has certain included angle between the axis of two mount pads that are connected with vehicle body, automobile in the process of moving like this, vehicle body is applied to resultant direction on the mount pad and the axis of mount pad reaches unanimity, the power that the binding bolt of connection vehicle body and mount pad is subjected to diametrically is less, binding bolt is difficult in vehicle traveling process because of the vibration of vehicle body loosening phenomenon taking place, binding bolt has connectivity robustness preferably, connectivity robustness between vehicle body and the mount pad is good, has improved the driving safety and the traveling comfort of automobile.
Description of drawings
Accompanying drawing 1 is the block diagram of the utility model vehicle rear axle assembly.
Accompanying drawing 2 is front views of the utility model vehicle rear axle assembly.
The specific embodiment
As can be seen from Figure, the agent structure of the utility model vehicle rear axle assembly is shaft-like back axle body 1, two ends are provided with joint pin 3, coil spring installation portion 4, rear shock absorber installation portion 5 respectively symmetrically on it, also be respectively equipped with one and be used for the mount pad 2 that is connected with vehicle body on described two joint pins 3.
After this back axle assembly is assemblied on the automobile, between coil spring installation portion 4 on it and the vehicle body coil spring is installed, between rear shock absorber installation portion 5 and the vehicle body shock absorber is installed.These shock absorbers and coil spring are used for automobile vibration damping is in the process of moving helped improving the traveling comfort of driving.
Above-mentioned joint pin 3 tilts towards the outside, end of back axle body 1, and mount pad 2 vertically is fixedly connected on the outer end of joint pin 3.Axes intersect on two mount pads 2, has an angle α between the two axial lines, 100 °＜α＜160 ° wherein, the size of α is preferably between 1290 to 130 °, like this, vehicle body is applied to direction of making a concerted effort on the mount pad 2 and the axial direction basically identical of being located at the binding bolt 6 on the mount pad 2, and automobile in the process of moving, binding bolt 6 is difficult for producing loosening, thereby has guaranteed very much the connectivity robustness between vehicle body and the back axle body 1.
In order to increase the fastness of joint pin 3, joint pin 3 is the outside of oblique agley back axle body 1 end, and the sweep on the joint pin 3 is an arc-shaped transition.
