Embodiment Construction

[0016] Now in conjunction with embodiment, accompanying drawing, the present invention will be further described:

[0017] The cylinder-auxiliary box assembly of this embodiment consists of a shift fork shaft 1, a cylinder 2, a No. A O-ring 3, a piston 4, a B-No. Wrinkled copper washer 9, hexagonal nylon lock nut 10, C size O-ring 11, hexagonal head bolt and spring washer assembly 12, rear support self-lubricating wear-resistant solid lubricating bearing 13, front support self-lubricating wear-resistant solid lubricating bearing 14 , Steel wire retaining ring 15 forms.

[0018] With the cylinder 2 as the main component, the rear support self-lubricating wear-resistant solid lubricating bearing 13 and the front support self-lubricating wear-resistant solid lubricating bearing 14 are respectively pressed into the Φ28 step holes on both sides of the Φ25.4 through hole of the cylinder 2, and respectively Use steel wire retaining rings 15 (2 pieces) to embed in respective retainin...

Abstract

The invention relates to a cylinder-secondary tank assembly for a heavy gear truck. A self-lubricating wear-resistant solid lubricating bearing is pressed in an inner hole of a cylinder type cavity in match with an excircle of a shifting fork shaft. The cylinder-secondary tank assembly creates friction between the cylinder inner hole and the shifting fork shaft under the eccentric force effect, but the self-lubricating effect creates an oil film on the surfaces of the cylinder and the shifting fork shaft to avoid the strain so as to guarantee the effective work of the cylinder-secondary tank. The quality main reason that the cylinder-secondary tank assembly has high failure rate is solved: a, the internal lubricating is not enough; and b, the wear-resistant degree when the cylinder-secondary tank assembly is subjected to the eccentric force is not enough. By improving the structure, the motive sealing reliability is improved and service life is prolonged, and the stability of the product quality is improved.

Description

technical field [0001] The invention relates to a cylinder-auxiliary box assembly for heavy gear trucks, which improves the reliability and service life of dynamic seals and improves the stability of product quality. Background technique [0002] The cylinder-auxiliary box assembly is a key component in the auxiliary box planetary mechanism of heavy-duty gear trucks, and it is used in conjunction with the air filter regulator and double H valve. The charging and exhausting of the cylinder-auxiliary box assembly is controlled by the double H valve, so that the shift fork shaft of the functional part on the cylinder-auxiliary box assembly performs telescopic movement, thereby driving the fixed shift fork on the shift fork shaft to move the sliding gear , By changing the transmission ratio between the gears in the gearbox, the high and low gears of the gearbox can be switched. [0003] The main structure of the cylinder-auxiliary box assembly in the prior art includes: a shift...
