Detailed description of the invention
The embodiment of automobile is as shown in Fig. 1 ~ 5: comprise vehicle frame 1, vehicle bridge 2 and the transverse arresting apparatus be arranged between vehicle frame 1 and vehicle bridge 2, transverse arresting apparatus comprises Panhard rod 4-2 and is arranged at the buffer structure at Panhard rod two ends respectively, the structure of each buffer structure is all identical, now only one of them buffer structure is described in detail, buffer structure comprise be arranged at connecting element on vehicle frame and by the corresponding end of connecting rod mechanism and Panhard rod 4-2 be in transmission connection under Panhard rod effect to the movable part that connecting element exerts a force, between connecting element and movable part, there is free gap.Movable part comprises the Rocker arm 5 that pivot center extends in left-right direction; rocking arm rotates and is arranged on rocker arm bracket 6-1; rocker arm bracket 6-1 is fixedly arranged on vehicle frame; connecting rod mechanism comprises the kinematic link 4-3 that two ends are connected with anti-sway bar link with rocking arm respectively; connecting element is positioned at the side of Rocker arm 5, and free gap is the circular gap 7 be arranged between rocking arm and connecting element.Connecting element comprises the block arc 6-2 with circular arc-shaped recess and the arc tile 6-3 arranged with the concentric of rocking arm, block arc is made up of elastomeric material, block arc sulfuration is fixedly arranged on the inwall of described arc tile; rocking arm have extend in arc-shaped depression portion and with the arc convex of arc-shaped depression portion normal-running fit; rocking arm is provided with the pushing tow face 8 be oppositely arranged with the circumferential both ends of the surface of block arc respectively in the both sides of arc convex, circular gap is arranged at the circumferential both ends of the surface of block arc with between corresponding pushing tow face.Figure middle term 4-4 represents the connecting bushing be hinged and connected of rocking arm and Panhard rod; Item 4-1 represents lateral stability rod bearing; Item 3 represents suspensions.
When running car is in roughness pavement, vehicle frame will produce the inclination of smaller angle, compression between vehicle frame and vehicle bridge or stretching exercise will drive lateral stability rod twisting by kinematic link, this twisting motion will react on rocking arm by kinematic link, now rocking arm is around own axis, because there is circular gap between the pushing tow face on rocking arm and the circumferential both ends of the surface of block arc, therefore rocking arm idle running, not to block arc power transmission, if the angle of roll of car body continues to increase, pushing tow face on rocking arm just starts to contact power transmission with block arc, and be made up of elastomeric material due to block arc, therefore the anti-roll rate of now lateral stability pole pair car body generation is also less, that is when vehicle frame produces smaller angle inclination, Panhard rod is in zero stiffness district and Low rigidity district, zero anti-roll moments and less anti-roll moments are produced to vehicle frame, thus reduce the angle of roll vibration of automobile, improve ride comfort, when automobile turning, vehicle frame produces large angle side inclination angle, Panhard rod applies antagonistic force by kinematic link, rocking arm to block arc, now the rotational angle of rocking arm is larger, rocking arm overcomes the elastic deformation amount of circular gap and block arc, Panhard rod provides larger torsional stiffness by rocking arm, block arc for vehicle frame, thus can effectively suppress vehicle frame to roll, and reduces the generation of vehicle rollover accident.Therefore when the utility model achieves car body little side tilt angle, the roll rate that Panhard rod produces is low, to improve travelling comfort, during the large side tilt angle of car body, the roll rate that Panhard rod produces is high, and along with the increase of car body side degree of tilt, its roll rate is non-linear increase also, thus effectively suppress car body to roll, improve driving safety, reduce the probability of occurrence of vehicle rollover accident.
In other embodiment of this automobile: buffer structure also can only have one, this buffer structure can be arranged at left end or the right-hand member of Panhard rod; Block arc also can be made up of rigid material; Connecting element may not be block arc structure, such as is a square block, rocking arm is provided with the pushing tow face for coordinating with square block pushing tow, and circular gap is in pushing tow face and square between the block; Movable part may not be rocking arm, such as be can the slide block of straight-line motion, slide block is in transmission connection by connecting rod mechanism and Panhard rod, the twisting motion of Panhard rod is converted into straight-line motion by connecting rod mechanism, connecting element is then a stop block structure, free gap is the rectilinear clearance be arranged between stop block structure and slide block, when vehicle frame low-angle rolls, Panhard rod band movable slider straight-line motion, slide block movement displacement is less and can not to stop block structure power transmission, when vehicle frame wide-angle rolls, slide block movement displacement comparatively greatly can to vehicle frame power transmission; Certain free gap also can not be established, now resilient snubber can be set between connecting element and movable part, resilient snubber is spring or cylinder etc., when frame sides degree of tilt is less, due to the application force of Panhard rod, the activity of movable part is not enough to the elastic limit overcoming resilient snubber, if the angle of roll of vehicle frame is larger, under the effect of Panhard rod, the activity of movable part is comparatively large and be enough to the elastic limit overcoming resilient snubber, thus provides larger anti-roll moments for vehicle frame.
Corner is correlated with the embodiment of variation rigidity transverse arresting apparatus as shown in Fig. 1 ~ 5: the be correlated with concrete structure of variation rigidity transverse arresting apparatus of corner is identical with the transverse arresting apparatus described in above-mentioned each automobile embodiment, be not described in detail in this, corner variation rigidity of being correlated with refers to that the change of rigidity is relevant to corner.
