Embodiment Construction

[0100] figure 1 It is a sectional view showing the overall structure of the clutch unit X in the embodiment of the present invention, figure 2 yes figure 1 Right side view of clutch unit X shown, image 3 yes figure 1 Left side view of clutch unit X shown, Figure 4 is along figure 1 A-A cutaway diagram, Figure 5 is along figure 1 Sectional view of the B-B line. 6 to 16 are diagrams showing main components of the clutch unit X. As shown in FIG.

[0101] The clutch unit X is incorporated into a seat lift unit for a motor vehicle that adjusts the height of the seat by, for example, operating a lever (refer to Figure 23 and Figure 24). Such as Figure 1 to Figure 5 As shown, the clutch unit X includes: a control rod side clutch part 11 arranged on the input side, and a braking device side clutch part 12 arranged on the output side with an anti-input blocking function.

[0102] Such as figure 1 , figure 2 and Figure 4 As shown, the lever-side clutch portio...

Abstract

To secure abrasion resistances of a brake-side outer race and a stopper contact portion, and to reduce cost, there is provided a clutch unit including: a lever-side clutch portion for controlling transmission / interruption of rotational torque to an output side with lever operation; a brake-side clutch portion for transmitting torque input from the lever-side clutch portion to the output side and for interrupting torque reverse-input from the output side, in which: the lever-side clutch portion includes an input-side member to which torque is input with the lever operation; claw portions (14g) extending in an axial direction are provided on an outer periphery of the lever-side outer race (14) of the input-side member; the brake-side clutch portion includes a stationary-side member restricted in rotation, the stationary-side member being constituted by a brake-side outer race (23) arranged while being separated from the lever-side outer race (14) in the axial direction and a cover (24) attached to the brake-side outer race (23) on a lever-side outer race (14) side thereof; claw portions (14g) of the lever-side outer race (14) are brought into slidable contact with an end surface of the brake-side outer race (23) with rotation of the lever-side outer race (14), the rotation being effected with lever operation; and the claw portions (14g) of the lever-side outer race (14) are allowed to come into contact, in a rotational direction, with lock portions (24e, 24f) provided on an outer periphery of the cover (24).

Description

technical field [0001] The present invention relates to a brake device having a lever-side clutch portion that transmits rotational torque from an input side to an output side, and a brake device that transmits rotational torque from an input side to an output side and blocks counter-input torque from an output side Clutch unit of the side clutch section. Background technique [0002] Generally, in a clutch unit using an engaging member such as a cylindrical roller or a ball, a clutch portion is arranged between an input side member and an output side member, and the clutch portion is configured to be formed on the input side member. Engage / disengage engaging elements such as cylindrical rollers or balls in the wedge-shaped gap between the output side member to control the transmission / blocking of input torque. [0003] This type of clutch unit includes: a lever-side clutch section that transmits rotational torque from the input side to the output side by incorporating it i...
