Abstract
The utility model discloses a kind of lightweight torque arm.Through hole (3) longitudinally through linking arm (2) is set on linking arm (2).Through-hole structure of the present utility model makes torque arm both reduce weight, its intensity is reached design requirement again.
Description
Technical field
The utility model is related to trailer technical field, more particularly to a kind of lightweight torque arm.
Background technology
With expanding economy, trailer has become the main means of transport in land route.And with trailer lightweight process
Development, it is desirable to trailer it is light-weighted simultaneously, keep due intensity；Therefore, the lightweight of each part of trailer, for vehicle
Lightweight is significant.
Utility model content
The purpose of this utility model is to provide a kind of lightweight torque arm for trailer, both reduces weight, makes its strong again
Degree reaches design requirement.
The utility model provides a kind of lightweight torque arm, and the through hole longitudinally through linking arm is set on the connecting arm.
Wherein, the through hole caves inward, and is step.
Wherein, 1/4 of the shoulder height H1 less than or equal to linking arm thickness.
Wherein, 3/4 of the area of through hole less than or equal to linking arm cross-sectional area.
Wherein, the material of the lightweight torque arm is aluminium alloy.
Wherein, it is arranged a pulling sleeve respectively in the fixing hole at linking arm two ends；The pulling sleeve is by inner sleeve and overcoat
Combine closely composition；
Wherein, the overcoat inner ring sets the groove being engaged with sawtooth, and sawtooth insertion groove is simultaneously combined closely；It is described outer
The material of set is high resilience polyurethane.
Wherein, the height of the sawtooth is the 1/5 of inner sleeve thickness.
Wherein, the inner sleeve periphery sets a plurality of depression striped, and the overcoat inner ring sets what is be engaged with depression striped
Raised line, raised line insertion depression striped is simultaneously combined closely.
Wherein, the depth of the depression striped is the 1/5 of inner sleeve thickness.
Beneficial effect：Through-hole structure of the present utility model makes torque arm both reduce weight, and its intensity is reached design again will
Ask；Supporting pulling sleeve is installed, small with bearing pin frictional force, long service life, security performance is significantly increased.
