Description
Technical field
The utility model belongs to the brake assembly component in automotive axle field, and in particular to one kind of automatic adjusting arm
New Joining Structure.
Background technique
In domestic automobile vehicle bridge, the control arm of automatic adjusting arm passes through parts and the Cam rests such as connecting bracket, bolt, this
Kind structure, the part of application is more, higher cost；It generally requires and tightens three bolts, assembly efficiency is lower.
Summary of the invention
The utility model is to solve in existing automotive axle since the control arm of automatic adjusting arm is using connecting bracket, bolt
Structure is connect with Cam rest, causes more using part, and higher cost, due to being connected by screw bolts causes assembly efficiency to drop
The problems such as low, provides a kind of connection structure of automatic adjusting arm.
The utility model adopts the following technical scheme that realization:
A kind of connection structure of automatic adjusting arm is applied in automotive brake assembly, and it is convex that brake camshaft passes through braking
Wheel support is simultaneously connected by the splined hole spline of the splined shaft of brake camshaft front end and automatic adjusting arm, which is characterized in that system
The axle journal front end of moving cam bracket is provided perpendicular to the boss of brake camshaft axis, and the front end face and rear end face of boss are
Perpendicular to the plane of brake camshaft axis, boss is equipped with circular through hole, and automatic adjusting arm has control arm, has on control arm
Circular through hole, rotational automatic adjustment arm are aligned the circular through hole of control arm with the circular through hole on boss, a cylindrical empty
The front end face of round tube of heart pipe structure is bonded with the rear end face of control arm, and the rear end face of round tube is bonded with the front end face of boss, and one
A flat-headed pin sequentially passes through circular through hole, the centre bore of round tube and the circular through hole of control arm on boss, and a split pin is worn
After crossing the radial through-hole of flat-headed pin bottom, the open end of split pin is bent.
Further technical solution are as follows:
There is at least one plain washer to be sleeved in flat-headed pin between split pin and control arm front end face, to adjust boss, circle
Gap between pipe and control arm.
Compared with prior art the beneficial effects of the utility model are:
A kind of automatic adjusting arm connection structure provided by the utility model, using flat-headed pin and circular tube structure, by cam branch
Frame is connected together with the control arm of automatic adjusting arm, instead of the connection structure of original bolt and bracket.Such structure subtracts
The quantity for having lacked Assembly part, reduces costs；It is bolted and is changed to tack pin connection, improve assembly efficiency.

Specific embodiment
The utility model is explained in detail with reference to the accompanying drawing:
The utility model provides a kind of connection structure of automatic adjusting arm, as shown in Figure 1, it is total to be applied to automotive brake
Cheng Zhong, brake camshaft 7 pass through brake cam bracket 1 and by the splined shafts of 7 front end of brake camshaft and automatic adjusting arm 4
Splined hole spline connection, which is characterized in that the axle journal front end of brake cam bracket 1 is provided perpendicular to 7 axis of brake camshaft
Boss 9), the front end face and rear end face of boss 8 are the plane perpendicular to 7 axis of brake camshaft, and boss 8 is equipped with circle
Through-hole, automatic adjusting arm 4 have control arm 9, there is circular through hole on control arm 9, and rotational automatic adjustment arm 4 makes the circle of control arm 9
Shape through-hole is aligned with the circular through hole on boss 8, front end face and the control arm 9 of the round tube 3 of a cylinder type hollow pipe structure
Rear end face fitting, the rear end face of round tube 3 are bonded with the front end face of boss 8, and a flat-headed pin 2 sequentially passes through the circle on boss 8
The circular through hole of through-hole, the centre bore of round tube 3 and control arm 9, after a split pin 6 passes through the radial through-hole of 2 bottom of flat-headed pin,
The open end of split pin 6 is bent.
As shown in Figure 1, can there is at least one plain washer 5 to be sleeved on flat-headed pin between 9 front end face of split pin 6 and control arm
On 2, for adjusting the gap between boss 8, round tube 3 and control arm 9, if the gap between above-mentioned three is larger, Huo Zhexu
Reduce the gap of above-mentioned three, the quantity of plain washer 5 can be increased.
