Abstract

The invention discloses an outer cylinder barrel of a shock absorber, which comprises a cylinder body, a shell cover in seal connection with the cylinder body, and a lifting lug fixedly connected to the lower part of the shell cover. In the outer cylinder barrel, the periphery of the shell cover is provided with a circle of seal ring groove below which a circle of catching groove is reserved; the cylinder body is in the seal connection with the shell cover in a way that the lower end part of the cylinder body is fastened in the catching groove after a seal ring is arranged in the seal ring groove; the fastening edge of the cylinder body is reinforced in a spot welding way; and the shell cover can be cast into a whole with the lifting lug on the lower part of the shell cover. The outer cylinder barrel has the advantages of relatively lower manufacture and detection cost and reduction in the cost of the product; and the shock absorber with the reinforced outer cylinder barrel is particularly applied to heavy-duty vehicles.

Description

technical field [0001] The invention relates to a piston barrel type shock absorber, in particular to an outer cylinder of the piston barrel type shock absorber. Background technique [0002] Among automobile shock absorbers, piston cylinder shock absorbers are currently the most widely used, and this type of shock absorber includes double-cylinder double-acting shock absorbers and single-cylinder gas-filled shock absorbers. The former includes a piston with a regulating valve whose upper part is connected to the piston rod, a working cylinder in which the piston can move and is filled with pressure oil (shock absorber oil) at both ends of the piston, and is set outside the working cylinder. The outer cylinder for storing oil and adjusting the amount of oil in the working cylinder; the latter includes a piston with a regulating valve whose upper part is connected to the piston rod, a working cylinder in which the piston can move, and a working cylinder in which the piston ca...
