Abstract
A brake system for a vehicle is provided which has liquid pressure supply units for outputting liquid pressure in response to braking operation, and wheel cylinders for braking wheels when actuated with supply of liquid pressure from the liquid pressure supply unit. The brake system is capable of actuating the wheel cylinders without delay despite a delay in the rise of the output liquid pressure of the liquid pressure supply units. The brake system has an accumulator, the output liquid pressure of which rises quicker than that of the liquid pressure supply unit, the output liquid pressure accumulated in the accumulator being supplied to the wheel cylinders with excellent response speed at the initial stage of braking operation.
Claims12
A brake system for a vehicle comprising a first liquid pressure supply unit for outputting liquid pressure in response to a braking operation, and a wheel cylinder operatively coupled to the first liquid pressure supply unit for braking a vehicle wheel when actuated with liquid pressure from the first liquid pressure supply unit;
- and a second liquid pressure supply unit having output liquid pressure which reaches the wheel cylinder quicker than that of the first liquid pressure supply unit, operatively coupled to the wheel cylinder, wherein said second liquid pressure supply unit is an accumulator and wherein the output liquid pressure of the second liquid pressure supply unit is selectively and independently of said first liquid pressure supply unit, supplied to the wheel cylinder at the time of said braking operation.
