Problems solved by technology

In addition, there are different length specifications for different markets, for example, requiring a reduction in the wheelbase of heavy vehicles, which in turn increases vibration problems because when a shorter wheelbase is used with a given differential offset , the inclination angle of the drive shaft increases

Embodiment Construction

[0026] in figure 1 Here, the reference numeral 10 generally indicates a frame of a commercial vehicle. The frame 10 is composed of two U-profile longitudinal side members 1, 1'joined together by a plurality of cross members (not shown). The engine 2 is mounted on the frame 1 and 1'together with the gearbox 4 through engine supports, each of which includes an engine support 9 and an engine gasket 3. The engine and gearbox together form an engine / gearbox assembly 20. The universal joint 5 is mounted on the gearbox 4, and the transmission shaft 6 transmits power from the engine / gearbox assembly 20 to the differential 7 via the second universal joint 11. The differential 7 distributes the engine power to the drive wheels 14 via the drive shafts 8. The engine 2, the transmission 4, the transmission shaft 6, the universal joints 5 and 11, and the differential 7 together form a power generation and transmission system. Other parts related to the power transmission system may be used, fo...

Abstract

A heavy vehicle (600) comprising a drive unit (602) arranged substantially along a longitudinal geometrical axis (608) of the vehicle. The drive unit (602) is inclined by being pivoted about an axis (610) whereby the drive unit (602) forms an angle (a) relative to the longitudinal geometrical axis (608). The pivot axis is situated in an intersectional point (610) between the longitudinal geometrical axis (608) and a longitudinal centre axis (611) of the drive unit (602), and the intersectional point (610) is situated in a position within the extension of the drive unit (602).

Description

Technical field [0001] The present invention relates to a system in a vehicle according to the preamble of claim 1, and a heavy vehicle, which includes a transmission unit arranged substantially along the longitudinal geometric axis of the vehicle. Background technique [0002] Heavy-duty vehicles such as trucks or buses include a power transmission system, or in other words, a drive train for transmitting power from the engine to the drive wheels of the vehicle. Generally, the drive train includes a transmission unit, that is, an engine and a gearbox as well as a drive shaft and a differential. The drive train is a well-balanced and optimized system to provide power to the vehicle in a safe manner and with low transmission vibration. [0003] Trucks are often cumbersome and huge, for example weighing several thousand kilograms and having powerful engines for driving the wheels. During certain adverse conditions, the high power output delivered by the driveline may cause undesira...
