Mechanical system for tilting cab of a vehicle

A mechanical system for a vehicle comprising a cab (1) and chassis (2), said mechanical system for tilting the cab (1) relative to the chassis (2), and comprising:

• a suspension arm (4) having a front end and a reward end, where the front end is pivotally connected to the chassis (2) forming a tilting pivot and the reward end is rigidly connected to a suspension bracket (3);
• a bush bracket (6) fitted to the underside of the suspension bracket (3);
• a link arm (7) having an upper end and a lower end, the upper end comprising a revolute joint that allows for only rotational motion and being connected to the bush bracket (6), and the lower end connected to clevis joint (8) and comprising a revolute joint that allows for only rotational movement;
• a screw (9) connected to the clevis joint (8) and comprising a rotational joint, the screw (9) meshing with a nut (10), where an inner thread of nut (10) matches an external thread of screw (9) and an outer surface of nut (10) is machined as a worm gear;
• a worm (11) rigidly connected to a first end of worm shaft (14) and meshing with the outer surface of nut (10);
• and
• an engaging clip (15) rigidly connected to a second end of worm shaft (14), where the engaging clip engages a detachable handle (12).
