Abstract
An interlocking brake system structure provides braking force in response to a force caused by operation of brake levers even when disk brakes are used for both front and rear wheel brakes. A saddle riding type vehicle includes an interlocking brake lever on a second handle from among the left handle and the right handle to interlock a front wheel brake device and a rear wheel brake device. An operation force distributor distributes operation force, caused by an operation of the interlocking brake lever, between the front wheel brake device and the rear wheel brake device. An interlocking wire receives and transmits the operation force distributed at the operation force distributor to the front wheel brake device.
Claims18
A saddle riding type vehicle, comprising:
- a front wheel;
- a rear wheel;
- a handle that includes a left handle and a right handle, and maneuvers a direction of the front wheel, one of the left handle and the right handle being a first handle, and the other of the left handle and the right handle being a second handle;
- a front wheel brake device that applies a braking action on the front wheel;
- a rear wheel brake device that applies a braking action on the rear wheel;
- a front wheel brake lever provided on the first handle to activate the front wheel brake device;
- an interlocking brake lever provided on the second handle to interlock the front wheel brake device and the rear wheel brake device;
- an operation force distributor that distributes operation force, caused by an operation of the interlocking brake lever, between the front wheel brake device and the rear wheel brake device;
- an interlocking wire that receives the distributed operation force, for the front wheel brake device, from the operation force distributor and transmits the received operation force to the front wheel brake device;
- and
- a displacement restrictor that restricts a displacement of the interlocking wire to less than a prescribed amount during the operation of the interlocking brake lever,
- wherein the displacement restrictor is disposed at a position relative to the interlocking brake lever so that the interlocking brake lever is operable while displacement of the interlocking wire is restricted,
- wherein the front wheel brake device comprises:
- a front wheel brake cylinder which is provided on the first handle together with the front wheel brake lever, a hydraulic pressure change being generated in the front wheel brake cylinder by each of
- an operation of the front wheel brake lever, and
- the transmission of the operation force through the interlocking wire;
- and
- a front wheel brake that operates in response to the hydraulic pressure change generated in the front wheel brake cylinder,
- wherein the rear wheel brake device comprises:
- a rear wheel brake cylinder which is provided on the second handle together with the interlocking brake lever, a hydraulic pressure change being generated in the rear wheel brake cylinder by the operation of the interlocking brake lever;
- and
- a rear wheel brake that operates in response to the hydraulic pressure change generated in the rear wheel brake cylinder,
- wherein the operation force distributor includes
- an operation force distributor support supported rotatably with respect to the interlocking brake lever, the operation force distributor support being located on the interlocking brake lever, and
- a wire connection portion that extends from the operation force distributor support.
