Embodiment Construction

[0012] figure 1 Among them, the outer ring (1) is fixed on the rear wall of the transmission housing, and a spring seat (4) and a spring (5) are housed inside it. The inner ring (7) is splined with the second shaft of the transmission through a splined shaft (8). The direction indicated by the arrow is the direction of rotation of the transmission shaft, that is, the inner ring (7) when the automobile advances. A shift fork (3) and two groups of wedges (2) and (6) are arranged between the outer ring (1) and the inner ring (7). The small angle rotation of wedge (2) and (6) is controlled by the pulling force of spring (5), frictional force and shift fork (3). figure 1 It is not difficult to see that when the inner ring (7) rotates in the direction indicated by the arrow, that is to say when the car is moving forward [the effect of the wedge (6) is not considered at this time, only the wedge (2) is considered] if the fork (3) If the wedge (2) is not controlled, the wedge (2) w...

Abstract

A parking brake is based on a roller external planetary bi-directional overrun brake. An external ring replaces external planetary block and heel. Wedges replace rollers. A fork controls wedges between the external and internal rings to go forward or backward or to stop. The both sides of the external ring are machined to be projected outwards at the portions engaged with the front and rear caps, of which the corresponding portions are machined to be recess for assembling with tight fit and being welded with low carbon steel electrodes with little annealed areas and hardness of HRC60 at its inner surface.

Description

Technical field [0001] The invention relates to an improved vehicle parking brake load, in particular to an overrunning clutch type vehicle parking brake device. Suitable for all kinds of large, medium and small cars. Background technique [0002] The present disclosed overrunning clutch type parking brake for automobiles has main parts including outer star wheel, pad, inner ring, shift fork, two groups of rollers, spline shaft, live pin, live pin seat, spring. It is an automobile parking brake in the form of a two-way overrunning clutch with a roller outer star wheel and a shift fork. The outer star wheel is connected to the rear wall of the transmission housing, and the inner ring is splined to the rear end of the second shaft of the transmission. A shift fork for controlling the rollers and two sets of rollers are arranged between the outer star wheel and the inner ring. One group is the rollers that allow the clutch to overrun when the car is moving forward, that is, ...
