Abstract

The invention discloses a transverse stabilizer bar for adjusting a vehicle roll angle with a lateral acceleration. The transverse stabilizer bar mainly comprises a left transverse stabilizer bar, a right transverse stabilizer bar, an electric servo push rod, a frame and a controller, wherein the left transverse stabilizer bar and the right transverse stabilizer bar are jointed with each other through a bevel gear train; a straight tooth is arranged at the upper end of one bevel gear in the bevel gear train; the straight tooth is engaged with a rack of the electric servo push rod; and the controller is connected with a vehicle CAN (Controller Area Network) bus. The transverse stabilizer bar for adjusting the vehicle roll angle with the lateral acceleration, disclosed by the invention, is advantaged in that the structure of the transverse stabilizer bar is reasonable; the transverse stabilizer bar is convenient in use; and as the rigidity of the transverse stabilizer bar is small, good comfort can be obtained when a vehicle runs on a pot-holed road in a straight line. During the turning of the vehicle, the electric servo push rod is controlled by the controller to drive the bevel gear train so that the torsion angle of the transverse stabilizer bar is increased; therefore, the anti-roll moment born on the vehicle from the transverse stabilizer bar is increased, the roll angle is reduced and good stability in operation is obtained.

Description

A kind of Panhard rod regulating vehicle roll angle with lateral acceleration
Technical field
The invention belongs to car chassis field, be specifically related to a kind of Panhard rod regulating vehicle roll angle with lateral acceleration.
Background technology
When motor turning occurs to roll, two, left and right wheel moves in the opposite direction relative to vehicle body, also moves in the opposite direction in the Panhard rod two ends be therefore connected with suspension swing arm, and now Panhard rod produces and reverses; Produce the Panhard rod of torsion on two points be connected with vehicle body, produce the power that two equal and opposite in direction directions are contrary, these two power form the moment that one puts on vehicle body, and this moment can suppress the inclination of vehicle body, improves the road-holding property of vehicle; But when vehicle travels at potted road surface, the relative motion of left and right two-wheeled also can make Panhard rod produce torsion, has a bank moment to vehicle body, makes vehicle body produce and rocks, affect travelling comfort.The rigidity of Panhard rod is large, then the road-holding property of vehicle is good, and traveling comfort is poor; Therefore, traditional Panhard rod is difficult to road-holding property and the ride comfort of taking into account vehicle.
Summary of the invention
For overcoming above-mentioned the deficiencies in the prior art, the present invention aims to provide a kind of Panhard rod regulating vehicle roll angle with lateral acceleration taking into account road-holding property and traveling comfort.
For achieving the above object, the present invention is by the following technical solutions: a kind of Panhard rod regulating vehicle roll angle with lateral acceleration, mainly comprise left Panhard rod, right Panhard rod, electrical servo push rod, frame and controller, described left Panhard rod, right Panhard rod are bonded with each other by bevel gear system, a finishing bevel gear cuter upper end in described bevel gear system is provided with straight-tooth, described straight-tooth is meshed with the tooth bar of electrical servo push rod, and described controller is connected with vehicle CAN bus
Described controller obtains the lateral acceleration a of vehicle by CAN y, work as a ywhen being less than or equal to the lateral acceleration a set in controller, electrical servo push rod is locked, and finishing bevel gear cuter does not rotate, and now the Panhard rod mode of action is identical with traditional Panhard rod; Work as a ywhen being greater than the lateral acceleration a preset in controller, controller controls electrical servo push rod and drives finishing bevel gear cuter, and actuating length and lateral acceleration are directly proportional, finishing bevel gear cuter makes left Panhard rod and right Panhard rod produce the contrary torsion in direction, now the twist angle of Panhard rod increases, the anti-roll moments that Panhard rod puts on vehicle body increases, and suppresses body roll, achieves the function regulating vehicle roll angle with lateral acceleration.
Described left Panhard rod, right Panhard rod adopt the Panhard rod that torsional stiffness is little.
The technical solution adopted in the present invention has following beneficial effect: the Panhard rod that the present invention adopts torsional stiffness little, and is divided into two sections, engages by bevel gear system.When vehicle is on hollow road during straight-line travelling, electrical servo push rod is in locking state, and bevel gear system does not produce motion, and now the mode of action of the present invention is identical with traditional Panhard rod, because the rigidity of Panhard rod own is little, good traveling comfort can be obtained; When Vehicular turn, controller controls electrical servo push rod and drives bevel gear system, increases the twist angle of Panhard rod, and the anti-roll moments coming from Panhard rod that vehicle body is subject to increases, and reduces angle of roll, obtains good road-holding property.

Detailed description of the invention
Technical scheme of the present invention is further illustrated by detailed description of the invention below in conjunction with accompanying drawing.
As Fig. 2, Fig. 3, shown in Fig. 4, a kind of Panhard rod regulating vehicle roll angle with lateral acceleration, mainly comprise left Panhard rod 1, right Panhard rod 2, and controller 7, described left Panhard rod 1, right Panhard rod 2 end is respectively arranged with finishing bevel gear cuter 3, 4, described left Panhard rod 1, right Panhard rod 2 is engaged by finishing bevel gear cuter 3 and finishing bevel gear cuter 4, form a bevel gear system, described finishing bevel gear cuter 4 upper end is provided with straight-tooth, described straight-tooth is meshed with the tooth bar of electrical servo push rod 5, described electrical servo push rod 5 drives finishing bevel gear cuter 4 by tooth bar with engaging of straight-tooth, finishing bevel gear cuter 4 drives Panhard rod 1 and 2 to make the two produce reversing sense again and reverses, described controller 7 is connected with vehicle CAN bus, and described finishing bevel gear cuter 3 makes bevel gear system structure more stable, and described movable parts is all installed in frame 6.
As shown in Figure 1, shown in Figure 5, described controller 7 obtains the lateral acceleration a of vehicle by CAN y, work as a ywhen being less than or equal to the lateral acceleration a of setting in controller 7, electrical servo push rod 5 is locked, finishing bevel gear cuter 4 does not rotate, now the twist angle of Panhard rod depends on beating of wheel, therefore at straight-line travelling or when turning to by a small margin, the rigidity of Panhard rod is very little, and vehicle can obtain good traveling comfort; Work as a ywhen being greater than the lateral acceleration a preset in controller 7, controller 7 controls electrical servo push rod 5 and drives finishing bevel gear cuter 4, and actuating length and lateral acceleration are directly proportional, finishing bevel gear cuter 4 makes left Panhard rod 1 and right Panhard rod 2 produce the contrary torsion in direction, now Panhard rod puts on the anti-roll moments increase of vehicle body, vehicle roll angle reduces, and vehicle can obtain good road-holding property; Achieve the function regulating vehicle roll angle with lateral acceleration.
More than show and describe groundwork of the present invention and principal character.The technical personnel of the industry should be understood; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and specification sheets just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
