Abstract
A lift truck 1 with a telescopic arm 3 comprises a front axle 6 and a rear axle 7 and a mechanical transmission to transmit the movement of the drive train 5 to the forward 6 and/or rear 7 axle or axles. The drive train 5 is oriented transversely to the truck 1 and the mechanical transmission is located in a central position. This arrangement permits easy access to the drive train and rapid exchange of the latter, so as to facilitate the maintenance and reduce the down time of the lift truck.
Claims27
In a lift truck with a telescopic arm, comprising a cabin containing a driver's seat and a heat engine located on opposite sides of the telescopic arm;
- said heat engine having an output shaft oriented transversely relative to the truck and said telescopic arm being articulated at the rear of the chassis;
- said chassis being supported by a forward axle and a rear axle, and comprising further mechanical transmission means connected to said output shaft for transmitting the movement of said heat engine to at least one of said front and rear axles;
- the improvement wherein the mechanical transmission means comprises an angled transmission with at least one output for driving an input shaft of a gear box located in a central position on said lift truck, said input shaft being substantially coaxial with a drive shaft of a hydraulic pump for said lift truck.
In a lifting truck with a telescopic arm, comprising a cabin containing a driver's seat and a heat engine located on opposite sides of the telescopic arm;
- said heat engine having an output shaft oriented transversely relative to the truck and said telescopic arm being articulated at the rear of the chassis;
- said chassis being supported by a forward axle and a rear axle, and comprising further transmission means connected to said output shaft for transmitting the movement of said heat engine to at least one of said front and rear axles;
- the improvement wherein the transmission means are mechanical transmission means comprising a gear box, wherein said gear box is located in a central position on said lifting truck and is connected to an angled transmission, and wherein said angled transmission is connected to said output shaft of said engine by means of a cardan joint.
In a lifting truck with a telescopic arm, comprising a cabin containing a driver's seat and a heat engine located on opposite sides of the telescopic arm;
- said heat engine having an output shaft oriented transversely relative to the truck and said telescopic arm being articulated at the rear of the chassis;
- said chassis being supported by a forward axle and a rear axle, and comprising further transmission means connected to said output shaft for transmitting the movement of said heat engine to at least one of said front and rear axles;
- the improvement wherein the transmission means are mechanical transmission means comprising a gear box, wherein said gear box is located in a central position on said lifting truck and is connected to an angled transmission, and wherein said angled transmission is connected to said output shaft of said engine by means of a driving shaft.
In a lift truck with a telescopic arm, comprising a cabin containing a driver's seat and a heat engine located on opposite sides of the telescopic arm;
- said heat engine having an output shaft oriented transversely relative to the truck and said telescopic arm being articulated at the rear of the chassis;
- said chassis being supported by a forward axle and a rear axle, and comprising further mechanical transmission means connected to said output shaft for transmitting the movement of said heat engine to at least one of said front and rear axles;
- the improvement wherein the mechanical transmission means comprises a mechanical angled transmission with at least one output, said output driving a gear box located in a central position on said lift truck.
