Disclosed is an engine mount for a vehicle including a membrane, which is an essential component of an engine mount for supporting a powertrain of the vehicle. The membrane may be deformed vertically and radially depending on an input amplitude so as to open or close bypass holes in upper and lower plates depending on the input amplitude. As such, it is possible to easily fulfill a function of isolating vibrations generated by the powertrain during idling and a damping function of controlling the behavior of the powertrain during traveling and it is possible to prevent the generation of abnormal noise attributable to cavitation and rattling phenomena.

A method for controlling a semi-active engine mount is provided to increase both NVH performance and driving performance of a vehicle and reduce noise and vibration generated under specific driving conditions. The method includes storing real-time vehicle speed data at intervals of a predetermined time and determining whether an engine is in an idling state. In response to determining that the engine is in the idling state, determining whether a current driving state of the vehicle corresponds to predetermined conditions in which noise and vibration performance is prioritized based on vehicle speed change information. The semi-active engine mount is adjusted to be in an on state, upon determining that the current driving state of the vehicle in the idling state of the engine corresponds to the predetermined conditions.

A power machine with an internal combustion engine and an in-line hydrostatic/hydraulic pump package includes a stiffening bracket which mounts a flywheel housing to the engine and is configured to change the natural frequency of the engine/pump package so that the engine firing frequency does not match the natural frequency of the engine/pump package.

A roll rod for a vehicle includes: a front insulator connected to a powertrain; a rod bracket to mount the front insulator on a front end portion of the rod bracket; a case bracket disposed outside the rod bracket and fastened to a vehicle body; a stopping rubber formed at a rear end portion of the rod bracket and disposed in an inner space defined by the case bracket; and a rear insulator formed between the rod bracket and the case bracket, where the rear insulator is secured to an outer side surface of the rod bracket and an inner side surface of the case bracket. The roll rod enhances an insulation rate against vibration of a powertrain and improves durability while reducing manufacturing costs through the simple structure and application of an extrusion molding method.

A vehicular motor mount made of a motor mount assembly and a frame mount assembly made of four components: a base plate, a capture ring, a post and a bushing. The post mechanically connects directly to the engine mount bracket and the base plate directly connects to the subframe of the vehicle. The polymer bushing is bonded directly to the post. The concave capture ring is directly connected to the base plate forming a capture housing with a cavity wherein the post and bushing of the motor mount assembly are constrained but not directly connected to the base plate or capture ring of the frame mount assembly. With no direct connection between the two assemblies, the engine is not directly connected to the subframe. This improves vehicle's ride. The bushing and the capture ring are common to all vehicular motor mounts. The motor mount may be replaced in pieces rather than in its entirety.

A seal for a wall of a vehicle includes a first plate that defines a first slot, and the first plate is to be coupled to the wall. The seal includes a second plate that defines a guide that extends outwardly from the second plate. The second plate is positioned adjacent to the first plate such that the guide is in communication with the first slot. The seal includes a third plate that defines a second slot that receives the guide, and the third plate is positioned adjacent to the second plate and is to be coupled to the wall.

An air intake system for a vehicle has a conduit having an internal wall forming an air passage. A deflector is disposed within the air passage. A restricting structure is disposed within the air passage between the deflector and a conduit outlet. The restricting structure defines at least in part an opening substantially laterally aligned with the deflector. The restricting structure has a lateral wall disposed downstream of the deflector and extending within the air passage. The lateral wall has a front surface generally facing a conduit inlet, and a plurality of surface-increasing features provided on the front surface. Each of the surface-increasing features has a length of at least 1 mm measured from the front surface in a direction normal thereto. An air intake system having a collector connected to the deflector and positioned to collect at least some moisture from air flowing past the deflector is also described.

The present disclosure provides a mount for a vehicle that is provided at a portion at which damping performance is desired and that is fastened by a stud bolt. The mount for the vehicle includes a flange into which the stud bolt is inserted and that supports the stud bolt, an insulator configured to surround the flange, a housing coupled to the other one of the vibrating body or the supporting body and to which the insulator is fixed, a chamber formed inside the housing as a space surrounded by the housing and the insulator, and the chamber is filled with a fluid. In addition, the mount for the vehicle includes a damping part mounted on the housing to divide the chamber into two spaces and to be disposed in the chamber. The mount for the vehicle is configured to appropriately absorb vibrations and reduce noise.

Suspension systems are provided where the lower control arm is allowed to separate from the engine cradle at prescribed conditions to deliver the proper wheel kinematics for select cases while maintaining structural integrity for all other load cases. A system includes a vehicle body structure, a wheel assembly, and a suspension system linking the wheel assembly to the engine cradle. The suspension system includes a link coupled with the engine cradle through a first joint and coupled with the wheel assembly through a second joint. The first joint is configured to release the link from the engine cradle under loads above a threshold force and above a threshold angle of the threshold force at the second joint, to provide the desired kinematics.
