Abstract
It is intended to provide a vehicle comprising a fluid working machine which can reduce wear of parts and be produced at low cost. The fluid working machine 11, 12 is provided with an eccentric cam 17, a piston 18A to 18F, a cylinder 19A to 19F, a drive rod 20A-20F having an engaging part 24 engaging with the piston and a contact part 25 contacting the eccentric cam 17, a holding member 34A to 34F surrounding the drive rod, a pressing member 40A to 40F for pressing up the holding member in a radially outward direction, and at least one holding ring 41 for holding the holding member from the outside.
Claims20
A vehicle comprising:
- a hydraulic pump;
- a hydraulic actuator which is driven by pressurized oil supplied from the hydraulic pump;
- wherein at least one of the hydraulic pump and the hydraulic actuator is a fluid working machine which comprises:
- an eccentric cam;
- a plurality of pistons arranged radially around the eccentric cam;
- a plurality of cylinders provided for the plurality of pistons, respectively, each of the pistons being configured to reciprocate along a radial direction of the eccentric cam by rotation of the eccentric cam;
- a plurality of drive rods which are provided for the plurality of pistons, respectively, and wherein at least one of said drive rods comprises:
- a main part that extends along a corresponding one of the cylinders;
- an engaging part that is formed at one end of the main part and is engaged with corresponding one of the pistons;
- and
- a contact part that is formed at the other end of the main part and contacts the eccentric cam;
- a at least one holding member that is arranged about the main part and extends along the axial direction of the drive rod;
- at least one pressing member which presses the respective holding members, outward in the radial direction of the eccentric cam;
- and
- at least one holding ring which is arranged on the radially outwards side of a plurality of holding members to hold the plurality of holding members from the radially outwards of the holding members.
