Liquid pressure generating apparatus and driving apparatus

Abstract

A liquid pressure generating apparatus including a pump, and two one-way clutches arranged coaxially with the pump drive shaft in a line in the axial direction on the side of a first axial direction. The pump case includes a projecting portion projecting from the corresponding pump case. Inner races of the respective two one-way clutches are integrated with each other and form a common inner race. Outer races of the respective two one-way clutches are formed independently from each other and are driven respectively by pump driving members different from each other, and directions of restricted relative rotation with respect to the common inner race are identical to each other. The common inner race includes a coupling portion to be coupled to the pump driving shaft on the side of the first axial direction with respect to the projecting portion.

Description

technical field [0001] The invention relates to a hydraulic pressure generating device and a driving device with the hydraulic pressure generating device. The hydraulic pressure generating device has: a pump with a pump casing and a pump drive shaft; One side in the axial direction of the shaft first direction side is arranged coaxially with the pump drive shaft in the axial direction. Background technique [0002] Conventional examples of a hydraulic pressure generator as an example of the aforementioned hydraulic pressure generator include, for example, hydraulic pressure generators described in Patent Document 1 and Patent Document 2 below. Specifically, both Patent Document 1 and Patent Document 2 disclose a structure in which the relative rotation direction of the outer wheel relative to the inner wheel is restricted (hereinafter referred to as Configure the two one-way clutches in the same manner as each other for the "object direction"), and the inner wheels of the t...

Problems solved by technology

[0005] However, in the above-mentioned Patent Document 1 and Patent Document 2, there is no mention of the support accuracy for the pump drive shaft.

Therefore, in the above-mentioned Patent Document 1 and Patent Document 2, it is obvious that there is no mention of ensuring the support accuracy of the pump drive shaft in a manner that can suppress the enlargement of the hydraulic pressure generating device, and it is still not possible to find a solution that can suppress the enlargement of the hydraulic pressure generating device. A structure that appropriately ensures the accuracy of supporting the pump drive shaft
