Embodiment Construction

[0034] Next, an embodiment of the present invention will be described with reference to FIGS. 1 to 4 .

[0035] In FIG. 1 , 11 is a master cylinder linked to a not-shown brake pedal of the vehicle, and 12 is a storage device of the present invention partially attached to the master cylinder 11 .

[0036] The master cylinder 11 is a tandem type (Dantem type) master cylinder in which the primary piston 14 and the secondary piston 15 are arranged in series in the cylinder block 13, and the first and second pistons are separated in the cylinder block 13 by two pistons 14 and 15. The pressurization chambers 16 and 17 are respectively connected to different brake piping systems of the vehicle (for example, the brake piping system on the front wheel side and the brake piping system on the rear wheel side). A return spring 18 is arranged between the bottom of the cylinder body 13 and the secondary piston 15 , and between the secondary piston 15 and the primary piston 14 . The primary...

Abstract

The present invention provides a brake fluid storage device for a vehicle and an auxiliary tank used in the storage device. The storage device can improve maintainability when the brake fluid is replenished, etc., and can also be reliably used when the vehicle is tilted. The brake fluid level in the auxiliary tank is suppressed from falling. A main tank (25) having a brake fluid injection port (28) at the top and an auxiliary tank (26) having communication ports (35a, 35b) with the master cylinder (11) are connected by pipes (27). Make the connection port (34) of the main tank (25) side of the auxiliary tank (26) extend into the tank body (26a), and arrange the opening end (40) of the connection port (34) on the pipe (27) from The auxiliary tank (26) is positioned farther from the main tank (25) than the conduction port (35a) toward the main extension direction of the main tank (25).

Description

technical field [0001] The invention relates to a storage device for a vehicle brake which stores brake fluid. In particular, it relates to a storage device for vehicle brakes having a main tank and an auxiliary tank connected to each other by piping, and an auxiliary tank used in the storage device. Background technique [0002] The storage device for replenishing the brake fluid is connected to the master cylinder of the vehicle brake. The storage device has a tank with a predetermined capacity for storing brake fluid, and allows the brake fluid to flow between the tank and the master cylinder through a conduction port provided at a lower portion of the tank. [0003] A master cylinder used in a vehicle brake is generally installed in an engine room near the foot of a driver's seat. Therefore, if the tank of the storage device is integrally attached to the master cylinder, depending on the type of vehicle, it is difficult for the operator to access the injection port whe...
