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；The inner sleeve periphery sets a plurality of sawtooth, and the overcoat inner ring sets the groove being engaged with sawtooth, sawtooth
Insertion groove is simultaneously combined closely；The material of the overcoat 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：The utility model makes suspended axle away from adjustable by the structure of adjustable through hole；In addition, torque arm is logical
Pore structure makes torque arm both reduce weight, its intensity is reached design requirement again；Supporting pulling sleeve is installed, with bearing pin frictional force
Small, service life is long, and security performance is significantly increased.Pulling sleeve and bearing pin frictional force are small, and service life is long, and security performance has aobvious
Write and improve.
