Background technology:
At present, China's off road wheeled vehicle adopts the double wish-bone arm type independent suspension more, and transverse arm is connected with car body with supporting base through bearing pin.Because the running environment of overland vehicle is comparatively abominable, the plain bearing easy abrasion in the supporting base causes between supporting base and transverse arm and produces the gap.If excessive clearance, rigid impact can take place in glancing impact supporting base and transverse arm, and wheel alignment parameter also is affected simultaneously, and the riding comfort and the stability of vehicle are under some influence.For addressing the above problem, satisfy the operating needs of off road wheeled vehicle, need a kind of transverse arm axial adjusting device of design.
Summary of the invention:
The purpose of this invention is to provide a kind of transverse arm axial adjusting device; Utilize the rotation of adjustment disk to promote moving axially of supporting base, thereby regulate the relative position of supporting base and transverse arm, to eliminate the endplay between supporting base and transverse arm; And simple in structure, easy accessibility.
For realizing above-mentioned purpose, the present invention adopts following technical scheme:
A kind of transverse arm axial adjusting device provided by the invention; This device comprises supporting base and is installed in the bearing pin between the supporting base, and bearing pin is connected with transverse arm, and supporting base is connected through bolt of rear end plate with car body; It is characterized in that: said supporting base can move at the axial direction of bearing pin; Said supporting base has the slotted hole that is used to install and fix bolt, has mounting groove on the end of said supporting base away from car body, and circular adjustment disk is installed in the said mounting groove; Said adjustment disk is an eccentric disc, and the center of gyration place of said adjustment disk has circular hole; Said bolt of rear end plate passes circular hole and is connected with car body with slotted hole, the diameter of said bolt of rear end plate, Circularhole diameter and slotted hole equal diameters; The eccentric throw of said adjustment disk is not more than the width between centers of said slotted hole.
In a kind of transverse arm axial adjusting device technical scheme provided by the invention, the slotted hole of said supporting base is that center line is symmetrical set with the axial line of bobbin.
In another preferred a kind of transverse arm axial adjusting device technical scheme provided by the invention, a week evenly is carved with scale on the said adjustment disk.
In the preferred a kind of transverse arm axial adjusting device technical scheme more provided by the invention, the eccentric throw of said adjustment disk is greater than 5mm.
Because the beneficial effect that has adopted technique scheme, the present invention to obtain is:
The present invention utilizes the rotation of the adjustment disk of eccentric dish-type to promote moving axially of supporting base, thereby regulates the relative position of supporting base and transverse arm, has simple in structure; Reliable operation is used flexibly easy accessibility; Volume is little, and the characteristics of light weight are specially adapted to off road wheeled vehicle; Also can be used for the heavy engineering vehicular field, transverse arm axial adjustment amount is generally 0～5mm.

The specific embodiment
Below in conjunction with embodiment invention is done further to specify.
Embodiment 1:
Shown in Fig. 1-8, a kind of transverse arm axial adjusting device of this example invention, this device comprises supporting base 3 and is installed in the bearing pin 2 between the supporting base 3; Bearing pin 2 is connected with transverse arm 1, and bearing pin 2 can rotate in supporting base 3, and transverse arm 1 links to each other with wheel set through ball end; Supporting base 3 is connected through bolt of rear end plate 5 with car body, and supporting base 3 can move at the axial direction of bearing pin 2, and supporting base 3 has the slotted hole 8 that is used to install and fix bolt 5; The slotted hole 8 of supporting base 3 is that center line is symmetrical set with the axial line of bobbin 2, has mounting groove 7 on the end of supporting base 3 away from car body, and circular adjustment disk 4 is installed in the mounting groove 7; Adjustment disk 4 is an eccentric disc, and the center of gyration place of adjustment disk 4 has circular hole 6, and a week evenly is carved with scale on the adjustment disk 4; The eccentric throw of adjustment disk 4 is greater than 5mm, and eccentric throw is the n among Fig. 5; Bolt of rear end plate 5 passes circular hole 6 and is connected with car body with slotted hole, the diameter of said bolt of rear end plate 5, circular hole 6 diameters and slotted hole 8 equal diameters; The eccentric throw of said adjustment disk 4 is not more than the width between centers of said slotted hole 8, and width between centers is the m among Fig. 4.
